Print | 10: Separations For a Repeat Length | Next >>
The list below is a guide to some of the basic stages involved in the preparation and exposure of separations for a repeat length of fabric. Obviously each length will at some point differ from the next. However there are some basic stages that need to be adhered to. This list should be used as a guide, but if at any stage in the process you are unsure then ask a member of staff.

1. In general you will require a separate separation on seritrace for each colour of the final design. However there are occasionally cases where more than one colour can be printed from one screen at a time. If for example each different coloured element in the design is sufficiently far apart from the next so as not to cause problems when pouring the dye into the screen and a small squeegee is used.
2. Before embarking on the production of separations ensure that your final design on paper will repeat from Left to Right, Use graph paper and a ruler. The final repeat paperwork design should also fit comfortably within your screen size. Double check everything before you begin.
3. Your final design artwork should be positioned so that it repeats within the graph paper which has the Maximum Image Area drawn in pencil, and a single Registration Line, which should be at least 2cm away from your Maximum Image Area.
Graph Paper
    Image Area drawn in pencil onto Graph Paper. e.g. 20” deep x 36” wide or whatever the maximum image area is for your screen. Some designs require less repeat depth than others.

Registration Lines and a L.H.S indicator at least 2cm away from the final image area
4. The above piece of graph paper and registered design should be taped down to a lightbox, then each individual colour separation should be drawn onto seritrace that has been taped over the top of this template. Each piece of seritrace is positioned over the top of the next until all separations are complete. This will ensure that all your separation will align to one another and that they all fit within the final Image Area and that all registration lines and L.H.S. indicators are in exactly the same place. Which is vital for the successful registration of your print.
5. All separations should be checked on the lightbox to ensure that they are opaque.
Remember if light gets through your separation the chance is that it will not expose properly.
